Awasher the cell 21, the conductor for the terminal 27 being boundbetween thenut 9 and the tubular rivet 5 through which the terminal 27passes. into contact with the rivets or lpoints 6, one after another,the cells 23 may be cut in, one at a time, thereby to increase thevoltage, the voltage available at each ofthe switch points 6 beingmarked on' the outer surface of the cover `3, as shown at 30. In thepresent embodiment of the invention all of the cells 22 are always inthe circuit. h

The tubular .rivets 15, cooperating with the nuts 28, constitute aconvenient means for coupling the battery cells 23 with the respectiveswitch points 6. The nuts 28 serve, further, to hold the cover 3 on thebody 1. Recalling that the casing generally is fashioned from pasteboard, such parts as the tubular rivets l5, 6, 10 and 5 may bemounteclin the casing readily and will have a firm and secure hold onthe casing, notwithstanding the frail material out of which the casingis made. The rivet 10, in particular, is well adapted to hold the switcharm 12 for swinging movement, and the rivets or 'switch points 6 willnot he torn out of the cover 25, notwithstanding the fact that theswitch arm travels repeatedly into and out of engagement with them.
